Cluster configuration file
AWS ParallelCluster version 3 uses separate configuration files to control the definition
of cluster infrastructure and the definition of custom AMIs. All configuration files use YAML 1.1
files. Detailed information for each of these configuration files is linked below. For some
example configurations, see https://github.com/aws/aws-parallelcluster/tree/release-3.0/cli/tests/pcluster/example_configs
These objects are used for the AWS ParallelCluster version 3 cluster configuration.
